-
摘要: 本文研究了Ｓ－盒的随机化及随机化ＤＥＳ的链式结构．给出了Ｓ－盒的随机化算法．基于此随机化及ＤＥＳ算法，讨论了一种抗差分密码分析的加密方法及一种构造Ｈａｓｈ函数的算法Abstract: The S boxes randomization and the chained texture of randomizing DES are studied in this paper.The algorithm on the S boxes randomization is given.An encryption method against differential cryptanalysis and an algorithm of constituting Hash function based on the algorithms of DES and the randomization are discussed.
